COLOSTRUM (Bovine) has been used in human health for centuries. Its enhanced amounts of growth factors and immunoglobulins have shown to provide excellent support for a healthy immune system. Studies suggest Lactoferrin to be a useful adjunct toward modulation of immune activity, in particular T-cell activation and antioxidant status.

Colostrum is the milk produced by the mammary glands of mammals in late pregnancy and the few days after giving birth. Bovine colostrum has been used in human health for centuries and Ayurvedic physicians have used it for both medicinal and spiritual purposes. Compared to ‘mature milk’, colostrum has higher amounts of immunoglobulins, growth factors, cytokines, and nucleosides than are found in milk. (References 1,4) They are also rich in oligosaccharides, antimicrobials, and immune-regulating factors.(Reference 1) The enhanced amounts of growth factors and immunoglobulins in Colostrum have shown to provide excellent support for a healthy immune system. Imupharm’s colostrum is collected within 48 hours of birth and freeze-dried into powder for encapsulation.

Bovine Colostrum
Bovine colostrum-based immune milk products have proven effective in prophylaxis against various infectious diseases in humans. (Reference 2) Good results have been obtained with products targeted against rotavirus, Shigella flexneri, Escherichia coli, Clostridium difficile, Streptococcus mutans, Cryptosporidium parvum and Helicobacter pylori. (Reference 3) Some successful attempts have been made to use immune milk in balancing gastrointestinal microbial flora.

Bovine colostrums are the "early" milk produced by cows during the first several days post-parturition. This "early" milk has a nutrient profile and immunological composition that differs substantially from "mature" milk. Included in the nutrient profile are higher amounts of immunoglobulins, growth factors, cytokines, and nucleosides than are found in milk. Bovine colostrums are also rich in oligosaccharides, antimicrobials, and immune-regulating factors. Available evidence suggests a beneficial effect of supplementation of bovine colostrums in improving body composition, aspects of athletic performance, diarrhea in persons with immune-deficiency syndromes, NSAID-induced gastrointestinal disturbances, and aspects of the acute phase response that occurs secondary to surgery. Specific hyperimmune bovine colostrums, produced to have high neutralizing titer activity against Cryptosporidia, H. pylori, measles, rotavirus, and Shigella sp., appear to have clinical utility in conditions associated with these infectious organisms.

The immunoglobulins of bovine colostrum provide the major antimicrobial protection against microbial infections and confer a passive immunity to the newborn calf until its own immune system matures. The concentration in colostrum of specific antibodies against pathogens can be raised by immunising cows with these pathogens or their antigens. Immune milk products are preparations made of such hyperimmune colostrum or antibodies enriched from it. These preparations can be used to give effective specific protection against different enteric diseases in calves and suckling pigs. Colostral immunoglobulin supplements designed for farm animals are commercially available in many countries. Also, some immune milk products containing specific antibodies against certain pathogens have been launched on the market. A number of clinical studies are currently in progress to evaluate the efficacy of immune milks in the prevention and treatment of various human infections, including those caused by antibiotic resistant bacteria. Bovine colostrum-based immune milk products have proven effective in prophylaxis against various infectious diseases in humans. Good results have been obtained with products targeted against rotavirus, Shigella flexneri, Escherichia coli, Clostridium difficile, Streptococcus mutans, Cryptosporidium parvum and Helicobacter pylori. Some successful attempts have been made to use immune milk in balancing gastrointestinal microbial flora. Immune milk products are promising examples of health-promoting functional foods, or nutraceuticals. This review summarises the recent progress in the development of these products and evaluates their potential as dietary supplements and in clinical nutrition.

Colostrum is breast milk produced after the birth of the newborn and lasts for 2-4 days. Colostrum is very important part of breast milk and lays down the immune system and confers growth factors and other protective factors for the young ones in mammals. This is the source of passive immunity transferred to the baby from the mother. The biological value of bovine colostrum in present day medical practice is documented in clinical trials and large databases containing case reports and anecdotal findings. The main actions include an antibacterial effect and modulation of immune response with the ability to neutralize lipopolysaccharides arising from gram negative bacterial pathogens. It has been found to be effective in infantile hemorrhagic diarrheas, other diarrheas and reduces the likelihood of disease progressing to hemolytic uremic syndrome. It has also been tested in H. pylori infection and diarrhea in immunodeficiency. Side effects of clinical relevance are limited to possible intolerance due to lactose and sensitivity to milk proteins.

Bovine colostrum has been shown to influence the cytokine production of bovine leukocytes. However, it remains unknown whether processed bovine colostrum, a supplement popular among athletes to enhance immune function, is able to modulate cytokine secretion of human lymphocytes and monocytes. The aim of this investigation was to determine the influence of a commercially available bovine colostrum protein concentrate (CPC) to stimulate cytokine production by human peripheral blood mononuclear cells (PBMCs). Blood was sampled from four healthy male endurance athletes who had abstained from exercise for 48 h. PBMCs were separated and cultured with bovine CPC concentrations of 0 (control), 1.25, 2.5, and 5% with and without lipopolysaccharide (LPS) (3 microg/mL) and phytohemagglutinin (PHA) (2.5 microg/mL). Cell supernatants were collected at 6 and 24 h of culture for the determination of tumor necrosis factor (TNF), interferon (IFN)-gamma, interleukin (IL)-10, IL-6, IL-4, and IL-2 concentrations. Bovine CPC significantly stimulated the release of IFN-gamma, IL-10, and IL-2 (p < 0.03). The addition of LPS to PBMCs cocultured with bovine CPC significantly stimulated the release of IL-2 and inhibited the early release of TNF, IL-6, and IL-4 (p < 0.02). Phytohemagglutinin stimulation in combination with bovine CPC significantly increased the secretion of IL-10 and IL-2 at 6 h of culture and inhibited IFN-gamma and TNF (p < 0.05). This data show that a commercial bovine CPC is able to modulate in vitro cytokine production of human PBMCs. Alterations in cytokine secretion may be a potential mechanism for reported benefits associated with supplementation.

Dietary supplements of bovine lactoferrin are purported in consumer literature to enhance and support the immune system response through their antioxidant, antibacterial, and antiviral properties. Our aim was to investigate more fully the potential immune modulating properties and antioxidant activity of an oral supplementation of bovine lactoferrin in humans. Using an intraindividual repeated measure design, 8 healthy males aged 30 to 55 years, self-administered daily for 21 days, one capsule of placebo for 7 days, followed by 100 mg of lactoferrin for 7 days, followed by 200 mg of lactoferrin for 7 days. Peripheral blood lymphocyte subset counts, T-cell activation, natural killer (NK) cell cytotoxicity, serum cytokine levels (tumor necrosis factor [TNF]-alpha, interferon [IFN]-gamma, interleukin [IL]-2, IL-4, IL-6, and IL-10), and serum hydrophilic, lipophilic, and total antioxidant capacity were repeatedly measured before and after each progressive supplementation. Statistically significant increases were found between presupplementation levels and levels after 200 mg of supplementation in total T-cell activation (as measure by CD3(+)) (P < .001), helper T-cell activation (as measure by CD4(+)) (P < .001), cytotoxic T-cell activation (as measured by CD8(+)) (P < .001), and hydrophilic antioxidant capacity (P < .05). No significant changes were seen in the other parameters measured. These results support the proposal that oral supplements of bovine lactoferrin may be a useful adjunct toward modulation of immune activity, in particular T-cell activation and antioxidant status.
